Description

Computes the absolute value of a vector on an element-by-element basis.

@@ -135,14 +135,14 @@ Functions pDst[n] = abs(pSrc[n]), 0 <= n < blockSize.

The functions support in-place computation allowing the source and destination pointers to reference the same memory buffer. There are separate functions for floating-point, Q7, Q15, and Q31 data types.
